Recap theory

General quick view of the theory 

Question -> raise your hand 

Not interest makes the to finish questions:  1 - 6 and 12

Photosynthesis

• Energy sun -> glucose 
• Water + carbon dioxide -> Oxygen and glucose  
• Symbols? 
• Metabolism example

Metabolism 

• Conversion of substances in a cell into other substances 
• Glucose is formed during photosynthesis
•  During metabolism glucose is converted into different products 

Body respiration

• Breakdown of glucose 
• Mitochondria inside cells 
• All cells, all species.
• More in muscles or more in skin?

Nasal cavity airwash

• Warmed up
•  Filtered 
• Humidified 
• Cilia can move mucus 
• + you can smell -> olfactory cells

Windpipe

• Horseshoe shaped rings of cartilage  
• Can it be closed?

Swallowing 

Gas exhange 

• Exchange of oxygen and carbon dioxide both involved in body respiration  

Abdominal breathing = diaphragm

Chest breathing = muscles, ribs and breastbone

Warm-blooded

• Constant body temperature 
• Body respiration maintains temperature

• Lower temperature -> more respiration
• Insulation

Avg. body temperature mammals ±36-38ºC

Avg. body temperature birds ±41 ºC

Cold blooded 

• Body respiration rate depends on outside temperature
• Cold? -> low body respiration -> not active
• The body temperature is the same as the temperature of their surroundings 
• Hibernation 

Overview of the theory?

• List of learning goals are on SOM 
• Only a summarize is not enough
• Practice with questions -> look back to your homework
•  Diagnostic test = to finish = Q1-Q6 + Q12

Welcome V3G

• Find your seat
• Grab your closed laptop, workbook and notebook
• Wait for the start of the lesson 

Agenda

• Practice test! 

Practice test can be found on SOM

• 6 questions
• Use of animals, but find the same principles as in humans
• Work alone 
• First 10 minutes in silence

How to answer biology questions?

• Multiple choice questions: only one question is correct. 
• Open questions: (als .. dan) : If ... then 
• Give your explanation if asked: .... is correct because... 
• Control if your answer is complete.

Again look at the test

• Control your answers if they are complete
• Discuss your answers with your neighbour 
• room to aks questions

Agenda last lesson

• What to bring to the test
• How to prepare
• Time to prepare 
• Measurement long volumne 

What do you bring to the test

• Pencil
• Calculator 
• English - dutch wordbook without any notes. Notes will be considered as " fraude " .  

Time to prepare

What: make assigments / summarize / mindmaps/ ask questions

How: individual or with the person next to you

Where: in the classroom

Done? Start working on homework other subjects

Long volume

• Iedereen gebruik een persoonlijk buisje
• Blaas zoveel mogelijk lucht in het buisje
• Vergelijk je resultaat met de gemiddeldes 
• Verschil man / vrouw, sporter / geen sporter
